How to Change Your S550 Mustang’s Cabin Air FilterLast Updated August 8, 2023 | Hamilton Schutt
A fresh cabin air filter will keep pollen, smoke, mold, and dust from polluting your S550’s interior. On average, you should replace the cabin filter every 10,000-20,000 miles to improve airflow, eliminate bad odors, and keep your windows from fogging up. This guide will walk you through how to replace a bad cabin air filter and give you some filter replacement options for your 2015-2023 Ford Mustang.
Filter Replacement Process
Replacing your S550’s air filter only takes 10-20 minutes and can save you upwards of $40 over the dealership’s rates. This process is the same for all 2015-2023 Mustangs.
- T20 Torx Driver
- Flashlight (Recommended)
Step 1: Open Glove Box
Open your empty glove box to the extended position and push the track on the right side in, up, and out to release the glovebox from the dash.
Step 2: Remove Glove Box
Push the sides of the glovebox towards each other until the black rubber stoppers can clear the box housing. Then, let the box drop.
Step 3: Lift Cloth Panel
Lift the small panel cut into the cloth interface behind the glovebox out of the way. If the access panel doesn’t give you enough room, you can easily pull the entire interface out of the way
Step 4: Remove Airbox Cover
Locate the airbox cover and use the T20 Torx Driver to remove the single screw holding the cover in place. Take the airbox cover off and set it aside with the screw.
Pro Tip: It’s easier to access the screw from under the dash.
Step 5: Remove Old Cabin Air Filter
Locate the paper tab sticking out of the airbox and pull the old filter out. You can remove it easily by pulling it from under the dash.
Pro Tip: Before you install the new filter, check your airbox for stuck leaves, twigs, or debris.
Step 6: Make Sure Filter Arrow Is Pointing Toward Dash
Locate the arrow on the new filter and make sure it’s pointing towards the dash before you slide it into the box.
Step 7: Insert Cabin Air Filter Into Airbox
Push the new filter all the way into the box so that only the tab is sticking out.
Step 8: Reinstall Airbox Cover
Fold the tab up and reinstall the airbox lid. Use your T20 Torx Driver to replace the screw.
Step 9: Put Cloth Panel Back In Place
Flip the access panel closed again, or put the medium back in place if you pulled it out of the way.
Step 10: Reinstall Glove Box
Push the sides of the glovebox in until the black rubber stoppers can clear the box housing. Then, pop the box back into place.
Step 11: Reattach Glove Box Track
Connect the track arm to the larger hole near the top of the glove box. Push the arm in and slide it down to lock the glove box in place.
